2.2 Physical
The physical dimensions of the unit are shown in Figure 2. A three-point mounting is
provided on the case of the unit. The gyro should be attached by three screws
through the 3.5 mm (0.138”) holes in the mounting feet. To avoid distortion, the gyro
must be attached to a clean, flat surface, and the fasteners must be tightened evenly to
0.5 Nm (0.7 ft.lb.) torque.
